  • a predetermined reference signal can be sent through the electrical wires extending through duct 21, with the reference signal passing through the expanding measuring strips 1-12 attached thereto. If a particular measuring strip is caused to expand due to the formation of a particular blade member attached thereto, resistance of the measuring strip to the flow of electrical current will vary in accordance therewith.

It is, of course, evident that linear movement between the various axes can also be detected through the expansion of a combination of the various measuring strips. For example, movement in the direction of the arrow 28 as shown in FIG. 3 will result in the expansion of the particular measuring strips 1, 3, 6 and 7, respectively, which will generate specific output signals which can be used to establish a program for actuating the drive motors to result in hand 27 moving in the direction of arrow 28.

If inductive transducers are employed, each of the transducers is mounted on a blade member and is attached to a capacitor, whereby deformation of the blade results in a corresponding change in the inductivity of the transducer mounted thereon.
  • Such inductive transducers are also considered to be passive, in that, a reference signal must be initially provided through the various transducers. It is also possible to replace the passive transducers disclosed hereabove with active transducers which are capable of generating electrical signals as a direct result of the electrical and magnetic properties inherent in the materials forming the transducer strips themselves.
